Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a connecting device for connecting and fixing a sink and a cooking table, which are kitchen furniture, for example.

As shown in FIG. 1, among kitchen furniture, a sink 1 and a cooking table 2 are usually arranged adjacent to each other. Further, the sink 1 and the cooking table 2 are connected and fixed to each other by a connecting device 3 as shown in FIG. . That is, this coupling device 3 is
A connecting bolt 5 and a connecting nut 6 are inserted into mounting holes 4a and 4b formed opposite to each other in the respective side plates 1a and 2a, and are fastened to each other.

By the way, the positions of the mounting holes 4a and 4b do not necessarily face each other correctly due to processing errors or unevenness of the floor surface, and are often offset from each other. For example, as shown by the two-dot chain line in the figure, one of the mounting holes 4b
is shifted upwards from the other mounting hole 4a,
It becomes impossible to fasten the connecting bolt 5 and the connecting nut 6. Therefore, it may be possible to insert a spacer into the lower end of the sink 1 to raise the entire sink 1 and align the mounting hole 4a with the mounting hole 4b.

However, this time, a difference in level will occur between the top plates 1b and 2b, making it difficult to use and spoiling the aesthetic appearance. It is also possible to re-drill the mounting holes 4a, 4b at new locations, but in either case, it is time consuming. Misalignment occurs not only in the vertical direction but also in the horizontal direction, causing exactly the same problems.

The present invention was developed in view of the above circumstances, and its purpose is to provide an adjustment button with a fixing hole at an eccentric position and an uneven surface on the side panel of furniture, etc. Even if the mounting holes are misaligned and do not face each other, the adjustment button can be rotated to make the fixing holes face each other and engage the uneven surfaces to connect the coupling. It is an object of the present invention to provide a connecting device for furniture, etc., which enables secure fixing with a simple structure and improves workability.

An embodiment of the present invention will be described below based on the drawings. 3A and 3B show the adjusting bush 10. FIG.
This adjustment bushing 10 is made of a hard synthetic resin material or a metal material, and consists of a hexagonal flange 11 and a fitting part 12 that projects integrally with the flange 11. A fixing hole 13 passes through the flange portion 11 and the fitting portion 12 at a position offset from the center position 10 by a dimension A. The end surface of the fitting portion 12 has an uneven surface 14 that extends radially and continuously from the fixing hole 13 . Further, nail holes 11a are bored in the flange 11.

Two adjustment bushes 10 configured in this manner are prepared to secure furniture, etc. That is, the fourth
As shown in the figure, adjustment buttons 10 are installed in mounting holes 17 and 18 bored in opposing side panels 15a and 16a of adjacent furniture 15 and 16 such as sinks and cooking tables.
Insert the fitting part 12 of. At this time, the uneven surface 14 becomes the insertion side, and the flange 11 is naturally connected to each furniture 15,
It will be inside 16. Furthermore, there is no problem even if the mounting holes 17 and 18 are misaligned.

That is, as shown in FIG.
If the center position of the mounting hole 18 is O ₁ and the center position of the other mounting hole 18 is O ₂ , then S 1 in the vertical direction and S ₁ in the horizontal direction, respectively.
This means that it is off by S ₂ . Each mounting hole 17,1
Since the center positions O ₁ and O ₂ of 8 are also the center positions of the adjustment button 10, by rotating this, the center locus of the fixing hole 13 on the mounting hole 17 side can be changed.
T ₁ , the center locus of the fixing hole 13 on the mounting hole 18 side is
T ₂ , each forming a circular shape. Each center locus T ₁
and T ₂ intersect in two places, at least one place.
With this intersection position X ₁ and X ₂ , the fixing holes 1 of each other
This means that the center positions of 3 and 13 exactly coincide.
Then, the adjusting bushes 10, 10 are fixed by driving nails 19, 19 through the respective nail holes 11a, 11a. Finally, the connecting bolt 2 which is the connecting tool 20
1 and the connecting nut 22 are inserted into the fixing holes 13, 13 and fastened, the uneven surfaces 14, 14 will engage with each other and there will be no displacement thereafter. Conversely, by screwing together the connecting bolt 21 and the connecting nut 22, the uneven surface 14,
After engaging 14, each adjustment bush 10, 10 may be fixed with nails 19, 19. Furthermore,
After fixing one adjustment bush 10 in advance, rotate the other adjustment bush 10 to ensure that the fixing holes 1 of each other are fixed.
Alternatively, the uneven surfaces 14, 14 may be engaged by searching for a location where the center positions of the surfaces 3, 13 match.

In reality, it is very difficult to check whether the center positions of the fixing holes 13 are correctly aligned while rotating the adjustment bush 10.
Therefore, after inserting the connecting bolt 21 and the connecting nut 22 into the fixing holes 13, 13, adjust the adjusting bush 1.
It is easy to check whether or not they can be connected to each other by rotating 0 and 10.

In addition, if the center trajectories T ₁ and T ₂ of the fixing holes 13 do not intersect with each other, their centers will not face each other and it will be impossible to connect the connector 20. In this case, however, the attachment holes 17 and 18 This only occurs when there is a large discrepancy that is unthinkable, and according to common sense, it almost never exists. Each of the center trajectories T ₁ and T ₂ is a circle whose radius is the dimension A, which is the eccentricity of the fixing hole 13. In other words, the adjustable range is twice the dimension A, which is extremely large.

Moreover, this type of connection device can be applied not only to sinks and cooking tables, but also to anything that is properly adjacent to each other and needs to be connected.

Note that the shape of the uneven surface 14 provided on the adjustment button 10 is not limited to the radially continuous uneven surface as in the above embodiment, but may also be an uneven surface provided with a large number of small protrusions, in short, they can easily engage with each other. That's fine.

As explained above, according to the present invention, mounting holes are provided in opposing side panels of adjacent furniture, adjustment buttons are inserted into these mounting holes, and fixing holes provided eccentrically in these adjustment buttons are installed. The adjustment bushes are rotated to face each other, the uneven surfaces of the insertion side end faces of the adjustment bushes are engaged with each other, and the connectors are inserted into the fixing holes and fastened together to connect and fix furniture, etc. It is something. Therefore, by providing an adjustment button with a very simple structure, it is possible to connect easily and reliably, which improves work efficiency and improves the aesthetic appearance by eliminating misalignment of furniture, etc. play.
